Displaying the actual filename when the same file is uploaded multiple times

ajit — Thu, 12 Jan 2012 08:40:56 +0000

Hi!

In Typo3 when we upload the same file (i.e. file with the same name) multiple times in a page, The same name is displayed on the page but the link to the files is diferrent as the file is renamed when it is uploaded.

For example

Say we upload a file name test.txt two times, the file is saved in the uploaded folder as

test.txt

test_01.txt

but on the page it displays as

test.txt (links to test.txt )

test.txt (links to test_01.txt )

So in case for the second time if we want to display the real file name to which it is linked,

i.e. test.txt (links to test_01.txt ) as test_01.txt (links to test_01.txt )

Add the following line in your SETUP CODE

tt_content.uploads.20.linkProc.removePrependedNumbers = 0

This will display the full file name…

Conditional menu based on menu page-id

spabhat — Tue, 27 Dec 2011 12:16:00 +0000

Following code gives a nice way to have a custom content element as sub-menu item for each main menu item

lib.customMenu = HMENU
lib.customMenu {
 1 = TMENU
 1  {
        wrap = |

        NO.allWrap = |
        NO.stdWrap.htmlSpecialChars = 1
        NO.after.cObject = COA
        NO.after.cObject {
            20 = CASE
            20 {
               key.field = uid
               default = RECORDS
               default.tables = tt_content
               default.conf.tt_content < tt_content
               default.conf.tt_content.stdWrap.innerWrap >               

               14 < .default
               14.source = {$submenu_element_14}

               15 < .default
               15.source = {$submenu_element_15}

               16 < .default
               16.source = {$submenu_element_16}

               17 < .default
               17.source = {$submenu_element_17}

            }            

        }
        ACT = 1
        ACT.after.cObject < .NO.after.cObject
        ACT.allWrap = |
        ACT.ATagParams = class="act"
        ACT.stdWrap.htmlSpecialChars = 1

        CUR < .ACT
        CUR.ATagParams = class="cur"
    }
}

This code cannot be used as it is, you will need to make sure the DHTML/JavaScript code for the sub menu items are configured accordingly.

Display the value one object only when the other object value is faslse

ajit — Wed, 07 Dec 2011 10:14:42 +0000

Hello!

In some cases we want to display the value of object only when the value of the other object is false or null. For this to work we use the typoscript cobject with the negate option.

The Following code depicts how to display the PREVIOUS and NEXT buttons in the typoscript prev/next menu. When using the prev/next menu code the prev button does not appear on the first page and next button on the last. But for some purpose we need to have these buttons but without the link.

The following code helps to solve this problem.

lib.prevNext = COA
lib.prevNext{
1 = TEXT
1.value = PREVIOUS
1.stdWrap.if.negate =1
1.stdWrap.if.isTrue.cObject = HMENU
1.stdWrap.if.isTrue.cObject {
special = browse
special {
items = prev
items.prevnextToSection = 1
prev.fields.title = PREVIOUS
}

1 = TMENU
1.NO {
linkWrap =

stdWrap.htmlSpecialChars = 1
}
}

2 = HMENU
2{
special = browse
special {
items = prev|next
items.prevnextToSection = 1
prev.fields.title = PREVIOUS
next.fields.title = NEXT
}

1 = TMENU
1.NO {
linkWrap =

stdWrap.htmlSpecialChars = 1
}
}

3 = TEXT
3.value = NEXT
3.stdWrap.if.negate =1
3.stdWrap.if.isTrue.cObject = HMENU
3.stdWrap.if.isTrue.cObject {
special = browse
special {
items = next
items.prevnextToSection = 1
prev.fields.title = PREVIOUS
}

1 = TMENU
1.NO {
linkWrap =

stdWrap.htmlSpecialChars = 1
}
}
}

Display the page when it is completely Loaded

ajit — Wed, 07 Dec 2011 09:47:25 +0000

Hello All!

The following code helps you to display the contents of the page after it is completely loaded. It uses the JQuery for this purpose.

Initially wrap the whole page in a

tag and hide it using CSS.

The HTML code is as follows….

…..

.
.
.
.
.

The Css for the div is as follows
#my_testid{
.
.
.
display:none;
}

Now Using the jQuery change the display property when the page is completely Loaded. For this to work we have “window.onload” option in jQuery

Display Image when both path and file name are in two fields

spabhat — Wed, 16 Nov 2011 11:30:00 +0000

The following code gives an overview of how to display an IMAGe when 2 fields are involved.
That is one contains the image path “fileadmin/templates/imgs/” and the other field has the image name “mylogo.png”

10 = IMAGE
10 {
    file.import {
         cObject = COA
         cObject {
             10 = TEXT
              10.data = field:image_path
             20 = TEXT
             20.data = field:image_name
         }
    }
}

Hope this helps.

Translate field in FCE

spabhat — Fri, 16 Sep 2011 07:30:00 +0000

Generally FCE cannot be translated, like normal tables. How we may use two fields like field_fr, field_en, and then display the related info according to the language.


EX:
      
10 = COA     
10 {     
    #Translation for primary language (L=0)
    30 = TEXT
    30.field = field_slide_info
    30.stdWrap.wrap = |
    30.if {
        value = 0
        equals.data = gp:L
    }

    #Translation for second language (L=1)
    40 = TEXT
    40.field = field_slide_info_en
    40.stdWrap.wrap = |
    40.if {
        value = 1
        equals.data = gp:L
    }
}

Tesseract Tips / Notes

spabhat — Fri, 16 Sep 2011 06:30:00 +0000

DATA FILTER:

Clear Filter/Query Cache: In some situations when “Additional SQL” field is cleared, the dataquery may still be using the cached value from this field.
In such case we should add following URL Parameter, which informs DataQuery to re-build the query from scratch.

EX:
www.example.com/?clear_cache = 1

Using main.subtable: When we wish to apply a specific condition to a sub-table, the query is applied on the JOIN itself:

EX 1:
subtable.uid = vars:event
maintable.uid = varsproject

This is translated to someting like this:

SELECT maintable.*, subtable.*
FROM maintable JOIN subtable
ON maintable.event_id = subtable.uid AND subtable.uid = 20
WHERE
maintable.uid = 45

However, if we add main.subtable.uid… the query gets converted to as shown below:
EX 2:
main.subtable.uid = vars:event
maintable.uid = varsproject

This is translated to someting like this:

SELECT maintable.*, subtable.*
FROM maintable JOIN subtable
ON maintable.event_id = subtable.uid
WHERE
subtable.uid = 20 AND maintable.uid = 45

Avoid translation of field using TCA and l10n_mode

spabhat — Fri, 16 Sep 2011 04:54:00 +0000

For a field which must not really be translated (such as a event date)

l10n_mode : exclude ( do not translate this)
l10n_display : defaultAsReadOnly ( show field as read only in translated
records)

This way translators see the field data, but can’t change it. This is the most logical for such a field.
Please refer doc_core_tca for more details about these two settings.

Displaying page title : Various methods

spabhat — Mon, 12 Sep 2011 15:10:00 +0000

Getting page title for a specific page (using uid)

METHOD 1:

temp.pTitle = HMENU
temp.pTitle {
special = list
special.value = {$my_page_uid}
1 = TMENU
1 {
NO {
doNotLinkIt = 1
}
}
}

METHOD 2: (The localization may not work fine in the below method)

lib.pagetitle = RECORDS
lib.pagetitle {
source.data = page:uid
tables = pages
conf.pages = TEXT
conf.pages.field = nav_title
}

Getting Current Page Title:

lib.pagetitle = TEXT
lib.pagetitle.field=title

Page title of parent page:

lib.pagetitle = TEXT
lib.pagetitle.data = leveltitle:-2
OR
lib.pagetitle = TEXT
lib.pagetitle.data = leveltitle:-3

Inserting page title within a HMENU

temp_pagetitle = TEXT
temp_pagetitle.data = leveltitle:-2

leftMenu = HMENU
leftMenu.stdWrap.preCObject < temp.leftmenu_pagetitle
leftMenu.1 = TMENU
leftMenu.1.wrap =
|

leftMenu.1.NO.wrapItemAndSub =
|

leftMenu.1.ACT = 1
leftMenu.1.ACT.wrapItemAndSub =
|

leftMenu.1.ACT.allWrap = |
leftMenu.1.CUR = 1
leftMenu.1.CUR.allWrap = |
leftMenu.2 < .1
leftMenu.3 < .2
